Alison has a secret. It's not the steamy fanfiction she writes late at night. It's not the fantasies she's been having about her brother's best friend. It's that she accidentally emailed both to her new roommate—who happens to be him. Now he's read every word. Every fantasy. Every detailed, blush-inducing scenario she dreamed up. And instead of being horrified, he's looking at her differently. The tension between them rises with every shared meal, every accidental touch, every loaded silence. But her brother has a strict "Bro Code"—best friends don't date sisters. Now Alison must navigate the minefield of her own desire, his growing interest, and a brother who would kill them both if he found out. She wants the guy of her dreams. But is he worth losing her family?
